If you’re a fan of Bighorn Arms actions you’ll be an even bigger fan of the PROOF Research pre-fit carbon fiber and steel barrels designed for the Bighorn Arms Origin action.
Our pre-fit Origin barrels are threaded and chambered for a simple install. These are shouldered barrels that come pre-headspaced and do not require gauges. Just spin them on, torque, and go shoot. Our drop-in barrels for Bighorn Origin actions are available in carbon fiber and steel in a variety of lengths and twist rates.
Up to 64% lighter than traditional steel barrels of similar contour.
Improved heat dissipation for cooler and longer lasting barrels.
Wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin.
Excellent erosion wear characteristics and corrosion resistance.
An optimum combination of high tensile strength along with requisite toughness to withstand extreme chamber pressures encountered during firing.
